`t`ul improved Advertising Apparatus, of

which the following is a spccilication.

My invcntion rclates to that description ot' advertising apparatus of which the advertiscncnts are succcsively and internittently cxposcd to View within the glazcd opening of a suitable case or cabinct and my invcntion has for its object 'to efi'ect i m provcncnts in apparatus of this type.

According to ny nventon, I mount n a suitable case or cabinet a pair of endless chains upon 'sprocket wheels which are fixed in'pairs upon their respective axles, means being' provided ifor tensioning purposes. The chains are arranged at a suitable distance apart and are connected by rods which are 'fixed at their ends in-the links of the chain, upon which rods I suspend -t'ranes, clips, or the like, to support transparent'designs, advertisenents, pret: erabl produced by ph'otographic processes as positives. Imnediately behind the front line ot' transparenees and opposite the glazcd opening of the case or cabinet .I fix a piece of, white opal glass. gronnd glass or other suitable material, which may serve a double purpose of reflecting light through the transparencies in daylight and of dispcrsing or ditiusingthe light froni the gas, clectric or other lamp placed behind said opal or other plate. A suitable spring, electric, water or other notor is mounted within the cabinct and suitable gearing is provided to drive the nechanisn ntermittently, giving a stationary period to the mechansm i I t n I'g. 3, the motor circuit 1 s closed and the chan s ust about to move upward. The

when the transparencies are opposite the glazed openings.

In the acconpanying drawings, Figure 1 is a vertical section of an apparatns with electric driving and lighting arrangement. Fig. 2 is a dctail View illustrating the chain of pictures; Fig. 3 is a detail view illustrating the ncchanism for controlling the motion ot' the chain and automatically switching into the circuit the motor and lanps al` ternatcly. Flg. t shows a 'front View with the 'front ot' the casing removed. Fig. 5 is v a dctailed view showing the nanner of suspondiug` the frames o.

i i i i r I i l a is a case, b is a lazed opening, c, c are sprocket wheels, and (l, d are the chains. The uppersprocket wheels are each mounted upon respective short axlcs, while the lower sprccket wheels are fixed to u shaft e car'icd in suitable bearngs. Any suitable goal-ing or mechanis n may be enployed for ntornuttently rotatng tne shaft e. That shown consists of an electric motor f which drives. through a worm g, a wenn-wheel [L fixed to a shaft z' cerried in bearingsk; bevel or nitcr gearing' transnit the rotary moton to a bevcl wheel m fixed to the shaft-..

Referring now to Fig. 2, il, d are the eudlesschains which are connected together at suitable intervals by rods n upon which the frames o for the transparenttor opaqmi pictures or advertisenents' are hung; 'the frames o muy be fixed to the 'ods n or they nay bo detachably connected thereto, as

shown in Fig. 5. I

The nternnttent motor of the chan of p ctures or advertsenents s, n the appentus illustrated, eti'ectcd by the nechanism illustrated in Figs. 3 and 4. n', 91,' indicates extcnded ends of the rods n (seen'lso in Fig. 2), and which is fittefwitha piston working in h suitable' dashpot -r and the up 1' end of which .is supported with a brac et hearing s, the-rod 7) being suitably weighted to autonatically fall, the speed of descent`of which is governed by the dushpot The red p carries a lifting catch lever t pivoted at t' and held by a spring u normally against a is a rod the lower end of stop u'. The tail of the lever t carries a i spring contact 'u which is capable of making` contact with eithenplate 'w or w according to the position of the lever t. The plote w is inthe motor circuit 1 and the plate 'w' is in the lamp circuit 2 In the position shown end n' of one of the rods n: then engages the catch of the lever t and rotates the letter sufticiently to bring the spring contact q in line wth the plate 'w when the continned movement of the chain carries with it the rodp and lever t in electric contact with the plate ;w and' the hearing 8.' When the rod has reached a certain height, the tail of the lover t comes into contact with a stop m, which trips the catch lever and disengages it from the end n' of the pin n; the rod then commcnces to descend slowly whereupon the !ever t returns to its normal position, breaking contact with w and making contact with the plate w' and thereby completing the lmp circuit. Simultaneously the motor cir- .5 cuit is broken and the motion of the chain arrested by a 'spring controlled stoplever y pivoted at y' to thc'case, the end'of which stop-lever has a hook y to engage the pin n'. Thus during the changing of the picture at the opening b, the lamps are not in the circuit, and during the statonary period L of the picture at the opening of the motor is not in the circuit. As the rod p descends, a pin z thereon (Fig; 4) comes .in contact with the lower part ot the stop level' y and disengages the hook 3 from the pin n' and at. about the same moment the contact "v leaves the plate 'w' and passes on to the latc'al extension of the plate w, again starting -tho mhtor.

The pictures of ad vertisments may be t-raispren t 'mr 'opaquc, it' the former, light from the lanp y' s diti'used through an opal glass (j which also .serves a reflector for '25 dayl'ight during the day time, the lamp circuit being broken by noving theswibch 3. I claim 1- 1. An advertising device comp'ising .a case, sp'ccket wheels thei-ein, chains on said wheets, advertising cards carried'by said -chains, electric lamps for illuminating said cards, an electric. motor for driving the sprocket wheels, an automatic switch -device alternatcly placing the motor and the lamps in circuitt and .means v for Operating the switch from the chains.

2. In advertising apparatus' of the type set forth, an intermittent drivingmechanism comprsing an electric'motor, procket 40 wheels and chains act'uated the'eby, projecting 'pins on said chains, a rod mounted to slide in bearings connected with one pole of a source of electrcty a catch`lever pivotcd on said 'rod and adapted to engage said pro t .ecting pins, an electrical 'contact piece on j said catch lever, a contact plate with which said contact piece is adapted to engage, said piate being connected with the other pole 'of the source of electricity through'the`motor,

60 automatic di sengaging means for said catch 'ing pins on said throug lever, and means governing the speed of v descent of said rod, as set forth.
